Have you designed a cool toy for your kids or used your own 3D printer to print a cool toy? If so then this contest might be of interest. 3D printer manufacturer Ultimaker have launched a competition to design 3D printable children’s toys. Called the Ultimaker 3D Printer Toy Design Challenge, entrants have the chance to win one of five Ultimaker 3D printers with a supply of PLA filament.

Entrants are asked to design a 3D printable toy in CAD file form and submit them via the GrabCAD site for judging. The judging panel consists of 3D printing professionals from Ultimaker, Protospace, GrabCAD, Ground3D and journalists from TCT Magazine and 3DPrintingIndustry.com, as well as PCMag.com Editor-in-Chief Dan Costa.

The entries will be judged on several criteria including creativity, feasibility in 3D printing on an Ultimaker and “overall coolness”. The challenge began on Wednesday and will run through until June 5th. The top 3 entries will win an Ultimaker 3D Printer and a supply of PLA filament (6 months for 1st prize, 3 months for 2 &amp; 3 prizes), the fourth placed winner will receive an Ultimaker kit with 3 months PLA and the fifth prize is the kit on its own.

Ultimaker provide their 3D printer in kits for self-assembly or fully assembled and feature a large build volume of 21x21x20.5 cm and can print at a resolution of 0.0125 mm. The submissions must be able to be scaled or cut into sections that fit within the maximum build volume and can be assembled together by snap fit, bolts, screws or glue.

The winners will be announced by July 5, 2013 and the contest sponsor will gain the intellectual property (IP) of the awarded entries.
